abstract="NbN phonon-cooled hot electron bolometer mixers (HEBs) have been realized with negligible contact resistance to Au pads. By adding either a 5 nm Nb or a 10 nm NbTiN layer between the Au and NbN, to preserve superconductivity in the NbN under the Au contact pad, superior noise  temperatures  have  been  obtained.  Using  DC  I,V  curves  and  resistive  transitions  in  combination  with  process  parameters  we  analyze  the  nature  of  these  improved  devices  and  determine interface transparencies.",
